Answer:

3) Obtuse

4) Right

Step-by-step explanation:

11 + 13 > 25 It is a triangle

11² + 13² = 25²

121 + 169 = 625

290 ≠ 625

Since hypotenuse is larger, the triangle is obtuse

21 + 28 > 35 It is a triangle

21² + 28² = 35²

441 + 784 = 1225

1225 = 1225

Since the hypotenuse is equal to the legs, it's a Right triangle

Find the coordinates of the midpoint of the segment joining the given points (0,2) and (6,4)

djyliett [7]

The coordinates of the midpoint are the average of the coordinates of the given points.

So, the x coordinate of the midpoint is the average of the x coordinates of the given point:

$\dfrac{0+6}{2} = \dfrac{6}{2} = 3$

And similarly, the y coordinate of the midpoint is the average of the y coordinates of the given point:

$\dfrac{2+4}{2} = \dfrac{6}{2} = 3$

So, the midpoint is the point $(3,3)$

Find the area of the rhombus

MAXImum [283]

<h3> Solution :-</h3>

Area of rhombus :-

$\bf \star \: \: \boxed{ \bf \dfrac{d_{1}d_{2}}{2} }$

$\sf \longrightarrow d_{1} = 4 \sqrt{3} + 4 \sqrt{3} = 8 \sqrt{3}$

$\sf \longrightarrow d_{2} = 4 + 4 = 8$

Area of rhombus :-

$: \implies \sf \dfrac{8 \sqrt{3} \times 8 }{2}$

$: \implies \sf 8 \sqrt{3} \times 4$

$: \implies \bf 32 \sqrt{3} \: {m}^{2}$
